Protein

Homeobox protein Nkx-3.2

Gene

NKX3-2

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

Transcriptional repressor that acts as a negative regulator of chondrocyte maturation. PLays a role in distal stomach development; required for proper antral-pyloric morphogenesis and development of antral-type epithelium. In concert with GSC, defines the structural components of the middle ear; required for tympanic ring and gonium development and in the regulation of the width of the malleus (By similarity).By similarity

Involvement in diseasei

Spondylo-megaepiphyseal-metaphyseal dysplasia (SMMD) [MIM:613330]: A skeletal dysplasia characterized by disproportionate short stature with a short and stiff neck and trunk, relatively long limbs that may show flexion contractures of the distal joints, delayed and impaired ossification of the vertebral bodies, the presence of large epiphyseal ossification centers and wide growth plates in the long tubular bones, and numerous pseudoepiphyses of the short tubular bones in hands and feet.1 Publication
Note: The disease is caused by mutations affecting the gene represented in this entry.
